TGVE

GitHub (30 sec)

  • Git beginner tutorial for LIDA interns can be found here
  • Free hosting for Open Source (OS) projects
  • Free Coninuous Delivery again for OS

Usin github pages

SPENSER

  • Wiki entry to do this

Using R (no time to discuss)

RStudio

RStudio

  • Showing the same results on TGVE using geoplumber R package
  • Reproducible R code example running TGVE: here

saferactive data on TGVE

Conclusions

  • We can process and visualize spatio-temporal data at scale
  • We can do this better than alternatives, there is better tech
  • TGVE deployment on GitHub pages are long term deployments

Thank you
